Michael Simon Wright, known as Simon, died in hospital
Two teenagers have been stabbed to death in London in unrelated attacks.
In the first, 19-year-old Kul Hawadleh, of Kingsbury, was killed at a petrol station in Wealdstone, north-west London, at 1930 GMT on Thursday.
Three hours later, Michael Simon Wright, 17, was found with fatal stab wounds opposite Maryland railway station in Stratford, east London.
The latest stabbings bring the number of teenagers killed in violent attacks in London this year to three.
In the same period last year, six teenagers had died in violence in the city.
In the incident at the High Weald Service Station in Wealdstone, another 19-year-old suffered stab wounds to his torso.
He is said to be in a stable condition in hospital.

Police said the pair were with two friends putting petrol in a car when they were approached by four to five males in their teens or early 20s.
There was an argument between the two groups before the stabbings and the suspects ran off.
In the Stratford attack, detectives believe Michael Wright could have been targeted as part of gang-related violence and appealed for witnesses.
Det Ch Insp Colin Sutton, of the homicide and serious crime command, said: "I am appealing to anyone who was in the area at approximately 2200 GMT who may have witnessed Michael arguing with other young black men in the vicinity of Maryland Station and nearby Ibex House."
Last month, 15-year-old Stephen Lewis was stabbed to death in Plaistow, east London, following a row at a party.
On Tuesday three boys aged between 15 and 17 were stabbed in a suspected gang fight on Kings Road, Chingford, east London.
Five teenagers - a 15-year-old, a 19-year-old and three aged 16 - have been arrested and bailed.
Police have not made any arrests over the other stabbings.
